When the nut 35 is tightened, the collar 3D vis forced against the rearbar, moving the rear bar up so that the Wall of the eye kl5 fits intothe notch in the upper edge of the rear bar.

From the foregoing it Will be seen that the bumper provided by myinvention is economical to manufacture and assemble. The bars are ofvery simple design and can be easily cut to shape, while the other partsrequired are few in numberwand easily made.
